media: atomisp: drop ATOMISP_MAP_FLAG_CONTIGUOUS

Drop the ATOMISP_MAP_FLAG_CONTIGUOUS hmm_alloc flag. After the contiguous
flag removal done in previous patches in this series it is never set.

And hmm_alloc already did a WARN_ON on the flag and otherwise ignored it,
proving that contiguous support was already never used.
